Rainbows! 0.9.0

Rainbows! is an HTTP server for sleepy Rack applications. It is based
on
Unicorn, but designed to handle applications that expect long
request/response times and/or slow clients. For Rack applications not
heavily bound by slow external network dependencies, consider Unicorn
instead as it simpler and easier to debug.

Changes:

This release introduces compatibility with Sunshowers, a library
for Web Sockets, see http://rainbows.rubyforge.org/sunshowers
for more information. Several small cleanups and fixes, too.
